JR group’s Railway Technical Research Institute is running a trial of the world’s first zero-loss electricity transmission system in Miyazaki Prefecture. Aiming to apply super-conductivity to the zairai-sen (conventional train) operation field, the organization has developed technologies to circulate liquid nitrogen inside thin cables of 10~17 centimeters in diameter. Currently, estimated electricity losses related to these train operations amount to approximately 5 % in Japan. Source: Nikkei / Energy Shift
